The Bosch Rexroth 4WEH 10 H4X/6EW110N9K4=CSA (R978909741) is a high-performance directional spool valve with electrohydraulic actuation designed for subplate mounting. This advanced control valve is capable of managing the start, stop, and direction of fluid flow within hydraulic systems. It features a robust housing that contains the main valve and control spool, along with one or two return springs for maintaining the spool in its central position when not energized. The model incorporates pilot control valves that can be actuated by one or two solenoids, providing precise movement of the main control spool by applying pilot pressure to spring chambers. This action allows for connecting or disconnecting specific ports within the valve, facilitating fluid flow direction changes in the hydraulic circuit. The unit also includes an optional manual override feature enabling manual operation in the absence of solenoid power. This particular Bosch Rexroth valve is engineered with internal leakage as part of its design principle, which may increase during its lifecycle. It utilizes external channels X and Y for pilot oil supply and return respectively, while also offering versions where these functions are internally managed. Available in various sizes (10, 16, 25), this component series (X) offers a maximum operating pressure of up to 350 bar and a maximum flow rate of up to 110 liters per minute. The valve's versatility extends through options such as different types of actuation (internal or external pilot control), DC or AC wet-pin solenoids, electrical connections for individual or central wiring configurations, as well as additional features like switching time adjustment, preload valves in channel P of the main valve, stroke setting and/or spool position monitoring. The Bosch Rexroth 4WEH series is designed to be adaptable to various hydraulic applications requiring reliable directional control with multiple actuation options to meet diverse system requirements.
